ABSTRACT:
An optical amplifier includes a plurality of amplifiers which are disposed between a first reflective mirror and a second reflective mirror of an optical resonator arranged with the first reflecting mirror and the second reflecting mirror in face-to-face relationship and are adapted to amplify light through induced emission; and a beam combining and separating device which is adapted to combine the light made incident thereupon from the plurality of amplifiers and cause the light to emerge therefrom in the direction of the second reflecting mirror and is also adapted to separate the light from incident thereupon after being reflected by the second reflecting mirror and cause the light to emerge therefrom in the respective directions of the amplifiers. As the combination and separation of the light are repeatedly effected, a beam of light having high energy amplified by the amplifiers is obtained.
